Description

TECHNICAL FIELD

The invention relates to the field of electromotion mixed dynamic vehicle; especially the motor drive and generation control tech in electromotion mixed dynamic vehicle, particularly in the electric/generating multiplex controlling technology.

BACKGROUND OF THE INVENTION

In recent years, in order to alleviate the tension of energy and worsening environment in mobile area, the study of new electromotion mixed dynamic vehicle of “energy-saving”, “environmental protection” has become a must trend. The so-called “hybrid electric”, is the multiplex of electric and other engines: when the mobile stars speeds up, it will use the permanent magnet synchronous motor/excitation motor as the multiplex motor to achieve the multiplex function of starting/electric power-assist; when the vehicle is slowing down or running normally, the permanent magnet synchronous motor/excitation motor will be used as the generator to achieve the energy feedback and charge to the battery.

The conversion of starting, electric power-assist and generating operating status needs a series of drive controlling technology to achieve, and there are many new problems and tech difficulties in achieving the drive controlling technology and hybrid mobile developing process.

For example: when the mobile starts in a low speed and high-speed power-assist according to automobile operating mode need, it needs a relatively higher electric torque, but the design theory of permanent magnetic motor limits the synchronous achievement of the low-speed starting the high torque and high-speed power-assisted the high torque. For example, under the same condition, the permanent magnetic motor at the rated speed of 800 r/min, its starting speed is much larger than the rated speed of 3000 r/min, but it cannot reach the high-speed power-assist due to its highest speed limit by the starting winding back electromotive force; the torque of the permanent motor designed as the rated speed of 3000 r/min is very small though it has a high torque power-assist in the high speed area. In other words, the permanent magnetic motor, which is designed as the low-speed starting requirement, cannot satisfy the functional need of power-assist in the high-speed area; while the permanent magnetic motor designed as the high-speed power-assist function cannot satisfy the need of the low-speed starting performance; and the contradiction between them cannot be negotiated.

For example: Nearly all the current low voltage/generating multiplex controlling tech adopts to the lower tube voltage-drop of MOSFET device or model to achieve the low voltage permanent magnetic brushless motor drive control. While the function of MOSFET power device is low voltage of heavy-current tube or model, for example: the working voltage of the power tube or model with 200 A-600 A is usually 150V, but the maximum working currency of 300V-600V tube or model is merely tens of ampere. Therefore, in the low-voltage/generating multiplex controlling system, it can only adopts to the heavy-current MOSFET tube or model. Then after the finish of the mobile electric working status, the engine can go into the generating condition naturally; and no matter if there is load or not in the generation output, the back electromotive power-assist will rise as the speeding up, which will lead to a higher back electromotive power-assist in the electric winding, and the back electromotive power-assist produced by it will be much higher than the normal voltage of the MOSFET tube or model. Taking the example of mobile 42V electric/generating multiplex apparatus system: 42V refers to the charging voltage in motor is 42VDC, the battery voltage adopted is safe voltage of 36V; the back electromotive power-assist of electric winding of the permanent synchronous motor designed as voltage of 36V, rating speed of 800 r/min is nearly 36V when working; however, the back electromotive power-assist of the one of 800 r/min can achieve more than 200 V under 6500 r/min, which is much higher than the minimal working voltage of MOSFET tube or model, damaging the MOSFET tube or model directly. So currently, in order to avoid the problems of the permanent magnetic 42V electric/generating multiplex apparatus system, many mobile producers, both in and out of China, still adopts to the excitation magnetic 42V electric/generating and its control system, though its torque and efficiency is inferior to the one in permanent magnetic synchronous motor.

Moreover, there will be two batteries and generating charging system in vehicle, no matter adopting to the high voltage or low voltage hybrid system; take the above 42V system for example, it comprises the two batteries of 12V, 36V and two generating charging systems of 14V and 42V Currently, the implementation of two batteries and generating charging system in most mobile companies adopts to this method: adopting to one generating and charging system to provide one kind of battery charging and/or loading electricity directly; to the generating charging system, it will use DC-DC to boost or drop the voltage, providing battery charging of another voltage and/or loading electricity. This method costs much and is low efficiency; especially for the DC-DC of high power, low voltage; and the controlling system of DC-DC has a tough tech problem, its designing cost is nearly one brushless permanent magnetic motor drive controlling system.

According to the tech difficulties above, nowadays, most of the various mobile companies adopts to the high-voltage hybrid system, that is a higher voltage battery, and the higher tube voltage, larger currency IGBT model to realize the motor drive control system, as well as adopt the permanent synchronous brushless sine wave motor and its weak magnetic drive controlling system; the weak magnetic drive controlling system, which adopts the weak magnetic way, can not only run the high torque in a low-speed starting, but also achieve the electric high-speed power-assist of the motor; accordingly, when the stator winding is stated in d axis, the weak magnetic controlling principle is to add the currency to generate the homo-polarity magnetic fields from stator field and relative rotator permanent magnetic, which will reduce the strength of the rotator permanent magnetic to achieve the goal of increasing the speed and control the output. However, the weak magnetic controlling is inclined to generate the electric rotator permanent demagnetization, and the requirement for circuit design is very high. Once there is something wrong with the circuit, the back electromotive power-assist will set all the controlling system on fire; and the motor will always exist the current input of weak magnetic, the temperature in motor will rise and be hot, which not only consume the energy, but also has the disadvantages of low efficiency, lots of problems, drop output torque, etc.

SUMMARY OF THE INVENTION

The position-velocity conductor in the permanent brushless synchronous motor (200) collects the relative position signal and speed-changing signal in the permanent magnetic rotator, and provide for the controlling circuit and drive circuit to achieve the controlling function.

The starting winding (210) U1, V1, W1 in the permanent brushless synchronous motor (200) connects with the three-phrase input in the high voltage rectifier chopper regulating circuit, when the engine is in low speed, if the starting winding (210) can not reach to the charging voltage in the high voltage battery (520), it can design the generating winding (250) U, V, W, which is two-rod output with the U1, VI, W1, and connects with the high voltage rectifier chopper regulating circuit (510), and the output direct currency will provide the high voltage 36V battery (5520) charging and loading electricity.
